' To all whom it may camera:

the provision of a music leaf turner of this Be it known that 1, WILLIAM C. ADAMs, a citizen of the United States, residing at Calistoga, in the county of Napa and State of California, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

The invention relates to music leaf turners, and more particularly to the class of portable key-operated music leaf turners.

The primary object of the invention is the provision of a music leaf turner wherein the leaves of music will be automatically turned in consecutive order upon the manipulation of a single key, thereby eliminating any in. convenience to the player of the musical instrument. i Another obj ect of the invention is the provision of a music leaf turner of this character wherein the construction thereof is novel in form so that theleaves of music will be automatically turned and maintained smooth for the convenient reading thereof.

A further. object of the invention is the provision of a :music leaf turner of this character wherein the music is supported in a convenient manner andv held in place without possibility of the falling, of the 7 music from. such positiomthe 'music being so novel manner.'-

clamped; upon the rack oft-he turner in a A still furtherobject of the invention is the provision of a' music leaf turner of this character wherein theportion of the music leaf turning arms overlying the sheets of the music are of" transparent material so that the matter contained on the sheets can be, conveniently read and such sheets automatically turned in their order. v

.A still further object of the invention is character wherein the same can be used upon the music support of a piano, organ or the like or may be used upon a rack or stand.

for supporting music, and in the latter instance will be operated from a foot pedal, the music being conveniently placed upon the turner and the leaves thereof engaged by the turning armso that the said leaves. will be automatically turned on the operation of the turner. Y 7 v A still further object of the'invention is the provision of a music leaf turner of this character which is extremely simple in construction, thoroughly reliable andeflicient in its operation, strong, durable andinexpensive n manufacture.

With these and other objects in view the invention consists in the features ofrconrearelevationthereof; Fig. 3 is an end edge elevation; Figdis a sectional view on the line H in Fig. 1;- Fig. 5 is a sectional viewon the line 55 of Fig. 1; Fig. 6 is a sectional viewon the line6-6 of Fig.1; Fig.

7 is a fragmentary plan view showinga slight modificatiomemploying afoot pedal; F ig. 8 is a perspective view of one of the music leaf turning arms, showing infull lines one position of the jointed sections thereof and in dotted'lines another position ofthe same; and. Fig. 9 is a sectional view thereof. Fig. 10 is a vertical sectional view through the sector showing the trip member ,pivoted to the under side thereof.

Similar reference characters indicate corresponding parts throughout the several views of, the drawings. I

Referring to the drawings in detail, the

music leaf turner comprises a base A which is preferably in the form of a board, havmg at "its front face, at a suitable distance elevated from the lower edge thereof, a

ledgerBconstituting a rack for the music,

while beneath the latter, medially of the base, is a rectangular shaped opening 10 and bridging'or closing this opening, at the rear side ofthebase is a supporting plate 11 preferably made frommetal, on which are fixed spaced vertically arranged bearings 12 which protrude forwardly through the opening 10 and have secured therein a vertical shaft or axle 18 which is preferably stationary and on which are loosely journaled 1 music leaf turning arms, the details of V which will be hereinafter fully described.

Each music leaf turning'arm comprises a swinging section 14 formed With'a widened end 15-which has mounted therein a hub 16 loosely journaled upon the axle 13, while at the opposite end'is pivoted at 17 the earportion 18 of afiat elongated sleeve 19 inwhich is detachably mounted a transparent finger or strip 20, the sleeve 19 being readily movable to horizontal or vertical position by reason of the pivotal connection 17 of its ear 18 with the outer or free end of the section 1 1-, while fixed to the plate 11 is a multiple leaf spring 21, the divided portions 22 of which play against the rounded edge 23 of the wider ends 15 of the respective sections 14: so as to hold the music leaf turning arms against free swinging movement and in adjusted position either at the right or left hand side of the music leaf turner.

Loosely journaled upon the lower end of the axle 13 is the hub 24. of the swinging arm of a sector 26 which is formed with a slot 27 through which is protruded the catch wing 23 of a trip member-29 pivoted at 30 to the under side of thesector 26, while formed on the respective sections 14: of the music leaf turning arms are the depending ears 31 provided with beveled end edges 32 to co-act with the cam edges 33 on the wing 28 and at opposite sides of a notch 31 therein for the positive locking engagement of the trip member 2-9 automatically with the music leaf turning arms. The member 29 is acted upon by means of a spring 35 which is carried by the pivot 30 so as to hold the wing normally protruding through the slot 27 in the path of the ears 31 and this member 29 is formed with a beveled trip extension which is adapted to protrude in its path of movement for engagement with a stationary tripping finger or projection 37 mounted upon the plate 11 at the left hand side of the bearings 12 so that when each music leaf turning arm is swung from right to left the latch member 29 will be automatically disengaged therefrom the armi25 being swung in a manner presently described.

Formed on the hub 24: of the arm 25 is a pinion 38 meshing with a toothed segment 39 journaled upon a stud shaft d0 mounted in the plate 10, and to this segment 39 is connected one end of a coiled retractile spring 11 which has its opposite end connected to an eye member 42 fixed to the plate 10 at the left of the segment 39 so that on the swinging of the segment in one direction the spring will be tensioned for automatically rotating the segment in the reverse direction. The segment 39 is designed to actuate the arm 25 having the sector 26 for the turning of the music leaf turning arms from right to left in succes sive order so that the sheets of music will be automatically turned accordingly.

Pivoted to the base A below the opening 10 therein is an operating key 13 having an out-turned free finger-engaging terminal 4 1 and to this key 43 is pivoted a link 45, the same being pivoted eccentrically to the segment 39 so that on depressing the key &3

the segment will be rotated against the resistance of the spring 11 for the automatic turning of the music leaf arms from right to left, the member 29 being designed to automatically release the arms when at the left of the music leaf turner and to auto matically engage the arms when at the right of the said music leaf turner.

Suitably mounted on the base A, centrally thereof, are spring held pivoted swinging clamps 46 which hold the music upon the base A to prevent the accidental falling of the same from the ledge 13, the fingers or strips 20 being swung to horizontal position when the music is to be placed upon the base A, and thereafter the said fingers or strips 20 are moved to vertical position to lie between the sheets of the music for the turning thereof from right to left when the key 43 is depressed.

In the operation of the music leaf turner the music is placed upon the base A so as to rest on the ledge B thereon, it being understood that initially the music leaf turning arms 1% have been swung from left to right, the clamps 16 serving to hold the music upon the base to prevent the accidental falling of the music from the ledge. The sheets of the music are positioned so as to overlie the respective transparent fingers or strips 20 when at the right hand side of the device so that on the locking engagement of the trip member 28 with the respective arms 1 1 in their order by depressing the key 44 each finger 20 will turn the sheet overlying the same so that when the sheet of music is at the left hand side of the device the said finger 20 will overlie the exposed face of the sheet. It is of course understood that one arm 1% turns but a single sheet of the music, the spring 4:1 being designed to rotate the segment 39 to swing the arm 25 carrying the sector 26 in a direction from left to right for the automatic engagement of the trip member 29 with the depending cars 31 on the arms 14: when positioned at the right hand side of the device, so that upon rotating the toothed segment 39 in a reverse direction the arms 14 will be singly turned from right to left when depressing the key at of the device, thereby turning in consecutive order the respective sheets of the music, the springs 22 being designed to serve as buffers for the arms 14s when swung from left to right of said device, and also the springs 22 act to hold the arms in a position when thrown from left to right or from right to left by engaging the side edges of the said arms, as is clearly shown in Fig. 1 of the drawings.

In Fig. 7 I show a slight modification, wherein the operating toothed segment .47 has pivotally connected eccentrieally thereto a depending rod 48 to which is pivoted a foot pedal 49, so that when the music leaf turner is placed upon a music stand the music can be turned automatically in consecutive order on depressing the foot pedal.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood and, therefore, a more extended explanation has been omitted.

Having thus described my invention,'I claim:

1. Amusic leaf turner comprising a base, plurality of music leaf turning arms mounted for swinging movement relative to the base, a sector mounted for swinging movement below thearms, a trip member carried by the sector and automatically engageable with the respective arms, means in the pathof movement of the said member to automatically releasethe same for the freeing of the music leaf turning arms, means for rotatlng the sector, means for returning the sector to normal position for engagement with the music leaf turning arms, and operatlve dlrectly on the means Copies of this patent may be obtained for 2.
